CULP, 011 ROANOKE, VIRGINIA mmsmz. rionmm Application filed May a1, 1931Serial No. 458,747.

This invention relates to improvements in eraser holders and has as itsprimary object to provide a novel compact device for holding a pencileraser and which devlce will be so constructed that the eraser may bereplaced by a new one when it becomes too worn for further use.

Another object of the invention is to provide a holder for an eraser soconstructed that the eraser will be very firmly and securely held inplace sothat there will be no likel1- hood of the same beingdisarranged, when in use, nor any likelihood-of the eraser beingseparated from the holder. 1

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawings,and specifically understood of course that minor changes may be made solong as they fall within the scope of the claim.

In describing my invention in detail, reference will be had totheaccompanying drawings, wherein like characters denote like orcorresponding parts throughout the several Views, and in which:

Figure 1 is a View in side elevation of the holder embodying theinvention, the component parts of the holder being illustrated in thepositions which they will occupy when the eraser to be held isintroduced into the device or is tobe removed therefrom.

Figure 2 is a longitudinal sectional view illustrating the relativepositions assumed by the parts of the holder when the eraser is grippedby the holder.

Figure 3 is a view similar to Figure 2 illustrating a modification ofthe invention.

Figure 4: is a view in end elevation of the eraser holder, the samebeing in the condition shown in Figure 1, and the eraser being in placein one element of the holder.

'The holder embodying the invention comprises a pair of tubular membersone of which is indicated by the numeral 1 and the other by the numeral2, and these members are preferably of resilient sheet metal and ofcylindrical form. The member 1 is telescopipointed out in the appendedclaim, it being embodiment ofthe invention shown in Figures 1 and 2 ofthe drawings, is closed at one end by a semi-spherical end portion3. The

member 1 at its other end is formed with longitudinal incisions 4providing a plurality of clamping portions 5 which are so formed as tobe relatively spread outwardly with respect to one another, and it iswithin the bounds of these members that the eraser, 0 0 which isindicated by the numeral 6, is to be fitted. v

The member 2 is of hollow cylindrical form and is slidable upon themember 1 and the member 1 is formed with two diametrically, I oppositelylocated and longitudinally extending slots 7 and headed studs 8 aremounted upon the inner side of the section 2, and in one position ofsliding movement of the member 2 on the member 1 is limited and, in oneposition of sliding movement of the member 2, the clamping portions 5will be relatively spread and, in the opposite or other position, themembers will be constricted by the riding of one end of the member 2over the said members, the elasticity of the eraser permitting of thisinward shifting or dis placement of the said clamping portion and theeraser being in this manner securely gripped by the said portions. 30 Inorder that the eraser may be held with certainty within the bounds ofthe portions 5, each of the said portions is formed with a stamped outspur 9, which spur is directed inwardly so as to become embedded in theeraser 6 when the eraser is inserted into the respective end of themember 1. The embodiment shown in Figure 3 is identical with that shownin Figures 1, 2 and 4 of the drawings except that in place of thesemi-cylindrical closed end 3 of the member 1, this end of the saidmember is formed with a hollow threaded socket 10 into which one end ofa. lead pencil 11 may be threaded, the threads of the socket entering,of course, into the wood body of the pencil. Parts in this figure,corresponding to parts in Figures 1 and 2 are indicated by the samereference numerals, primed.

What I claim is:

An eraser holder comprising telescopic tubular members adapted toreceive the eraser, the inner tubular member having incisions leading infrom its end and dividing said end into eraser clamping portions, saidinner member being provided at opposite sides with parallel slots, andstuds attached to the outer tubular member and slidably received in theslots and having heads extending into the inner member, the parts beingso arranged and proportioned that the outer tubular member holds thestuds in contact with the eraser and contracts the clamping portions ofthe inner member against the sides ofthe eraser when the same isprojected beyond the ends of both of the tubular members.

In testimony whereof I afiix my signature.

THOMAS H. JONES.
